REFRIGERATOR.

SPEIFIGATION form'ing part of Letters Patent No. 224,383, dated February10, 1880.

' Application filed December 10, 1879.

To all whom 'it may concern:

Be it known that l, HANS BRGGEN, ot' the and State of New York, haveinvented an Improved Ice-BX, of which the following is a specification.

My invention relates to improvements in iceboxes for the reception andcooling of barreled beer and ale, and for other similar purposes whichnecessitate frequent opening and closing of the cooling-chambercontaining the barrels of beer, &c. y

The object of my invention is to prevent the escape of the cold air fromthe ice-box and the access of the warmer exterior air to the ice-boxwhen the cooling-chamber containing the barrels ofbeer, &c., is opened,and also to insure a free circulation 4when the said chamber is v forthe barrels,

ing-chamber :is for the reception of valso showing volvlng cover closedthroughout said parts of the ice-box.

My invention consists of a cooling-chamber suitable bench for the kegs,&c., which coolcommunicates with an ice-chamber and has a sliding bottomand a revolving cover or front, which is yeonnectedgwith the slidingbottom of said chamber, so as to close or open (as the case may be) achamber below the cooling-chamber. The said lower chamber bottled beerand ale and other articles to be cooled.

rlhe invention also consists in providingr openings for the faucetspartly in the revolving cover, and in other details of improvementhereinafter more fully described.

In the accompanying drawings, Figure 1 is a vertical cross-section of myimproved icebox with -a beer-keg in position and the cooling-chamber forthe kegs closed, so as to permit a free circulation of cold airthroughout the ice-box. Fig. 2 is asimilar view of the icebox with therevolving coverof the keg-chamber thrown back to open said chamber andat the same time prevent the escape ,of the cold air and the admissionof warm aiA said view the connection between the reand the slidingbottom of the coohng-chamber. Fig. 3 is a partial front vlew of the box.i; f

Referring to the drawings, A is ai box or case having in its upperportion anice-chamber, B, provided with a grated ioor or bottom,

chamber and other kegs, &c., provided' with a.

a, andin the top or front of the case isasuitable door, b, to giveaccess to the ice-chamber B. Below the ice-chamber the case A is madebroader, so that the front b of the case below the ice-chamber Bprojects forward of the front of the ice-chamber.

C is the cooling-chamber or receptacle for the kegs of beer, ale, &c. Inthe chamber C is a bench or support, D, placed horizontally. The bench Dis composed of two iiat portions, d d', extending from the front b otthe case back to a little more than half the depth ot the lower part ofcase A, where a right-angular back portion, e, is joined to the rearedge ot the part d. Between the parts d and Il is a longitudinalopening, j', and on top of partd is the sliding bottom g of thecoolingchamber, which is adapted to slide forward against the part d, soas to cover the opening and to uncover said opening by sliding againstthe back c. Each side B of the case inclosin g the chamber Gis projectedforward to or beyond the front b.

Dis the revolving cover or front of chamber C. `Said cover or front isformed of' the segment of a cylinder of a length as nearly as possibleequal to the width of the case between its side walls, or, in otherwords, of about the same length as the chamber O.

Each end of the cover D is provided with an end piece, E, which abutsagainst the in side of the side B', and is connected with the side B bya pivot, such as is shown at fi, so that the said end E and the cover Dwill turn freely on said pivot. The pivots connecting the end pieces, E,with the sides B form the center of the circle, of which the cover D isa segment.

F is a lining-piece placed against the inside of eachside B', andhavingits upper edge curved to make a close connection with the curvededge of the end E when the cover is opened4 or closed, as shown in Figs.l and 2.

G is a rope or chain passed through or otherwise attached to the endpiece, E, just above the pivot t'. One end of this rope G is carrieddown between plate F and side B of the case in front of the pivot i,around and under the pin or pulley j, and is attached to the front edgeof the sliding bottom g, and the other end of said rope is carried downbehind the IOO pivot fi, around and under a similar pin or pulley, j',and likewise attached to the front edge ot the sliding bottom.

By drawing on the front end of cord G the sliding bottom g is moved overthe opening f, and by drawing on the back part of said cord the bot-tomgis moved back from over the said opening. Any other suitable mechanismfor connecting the sliding bottom g with the ends of the revolving covermay be substituted for that just described.

But one end E of the revolving cover D' is shown; but the other end isarranged in'precsely the same way as the one shown.

The sliding bottom gat the end (not shown).

is connected with the adjacent end E of the revolving cover in the samemanner as the one shown, so that the said sliding bottom will beoperated at both ends simultaneously.

Below the chamber C is a chamber, H, which may be used for bottled ale,beer, and other articles to be cooled.

Access is had to chamber H through a sul table door on the sides orfront ot' the case A, said door being shown in dotted lines.

The operation of the apparatus is as follows: Ice is placed in thechamber B, and the keg I is laid on the bench D, with its rear or innerend resting on the upright backe of the bench, whereby the keg is heldin an inclined position, with the spigot lying in a semicircular notch,o, in the top of front b', and projecting ont at the front ot' the case.The revolving cover or door D' being now drawn forward to the positionit occupies in Fig. l, it extends from the top of the front b of thecase to the bottom edge, h', of the front of the ice-chamber B, therebyclosing the chamber C. In the lower edge, u, of the said cover D' aresemicircular notches o', coinciding with the notches o, into whichnotches o' the spigot enters when the cover is Ashut down. By drawingforward the cover D' in this manner the rope G is caused to draw thesliding bottom g back, so as to leave the opening f uncovered, as inFig. 1. Thus arranged the cold air from the ice in chamber B passes downthrough the grated loor a and circulates through chamber C, around aboutthe keg I, and passes down through the opening fand space J, betweent-he bench D and the back of the case A, into the chamber H, where itserves to cool articles that may beplaced in said chamber.

The direction the cold aircan take when the ice-box is thus arranged isindicated by the arrows, whereby it is plainly shown that a completecirculation of the cold air through the chambers C II is obtained, andat the same time chamber C is closed by the revolving cover D', so thatno cold air can pass to the outside from said chamber, nor can any warmair enter it from the exterior.

Now, if it becomes necessary to open chamber C to remove the keg toplace another one on the bench, or for any other purpose, the revolvingcover D' is thrown back into chamber C behind the keg, so that its edgen will connect with the bottom edge, h', of the front of the ice-chamberB, and its edge-fn' will be in contact with the back of bench D, asshown in Fig. 2, and b'y this movement of cover D the rope Gr, acting onthe sliding bottom g, draws the said sliding bottom forward, so as tocover the opening f, as in Fig. 2.

In this way the front of chamber C and the bench D are exposed, so thatthe keg can be removed, if necessary. however, lthat part ot' chamber Cback of cover D' is shut in by the said cover, so that no cold air ispermitted to pass outside from the ice-chamber, nor can any pass out ofthe opening f, which is closed, nor can warm air enter the ice-box.Consequently, when the cover D' is thrown back to open chamber C at thefront, the admission of warm air and the escape of cold air areentirelyr prevented; but when the cover is closed down the cold air ispermitted to circulate freely throughout chambers C H.

The notches o o in front b' and cover D', respectively, are given thesame inclination as the spigot, so that said spigot will lic in the saidnotches without restraint and without interfering with the close joiningof the edge n of cover D and the top ofthe front b', as shown in Figs. 1and 3.

This arrangement permits a close and approximately air-tight connectionto be made between the front b' and cover D' when the spigots projectout, and also allows the cover D to be opened and closed when thespigots are in the keg.

l. The combination of the ice-box having ice-chamber B andcoolingchamber C with the revolving cover D', for operationsubstantially in the manner described.

2. In combination with the ice-box having chambers B, C, and H, thepivoted revolving cover D", substantially as described.

3. The bench D in chamber G, provided with the opening f, in combinationwith the sliding bottom g and the revolving cover D', which is connectedwith said sliding bottom g, substantially as described.

The above specification of my invention signed by me this 25th day ofDecember, 1879.
